Standard Test Method for Determining Transmissivity of Nonleaky Confined Aquifers by the Theis Recovery Method (Withdrawn 2024)
SIGNIFICANCE AND USE
5.1 This test method is useful for analyzing data on the recovery of water levels following pumping or injection of water to or from a control well at a constant rate. The analytical procedure given in this test method along with several others is used in conjunction with the field procedure in Test Method D4050.
5.2 Assumptions:
5.2.1 The well discharges at a constant rate, Q, or at steps of constant rate Q1, Q2 ... Qn.
5.2.2 Well is of infinitesimal diameter and is open through the full thickness of the aquifer.
5.2.3 The nonleaky aquifer is homogeneous, isotropic, and extensive in area.
5.2.4 Discharge from the well is derived exclusively from storage in the aquifer.
5.2.5 The geometry of the assumed aquifer and well are shown in Fig. 1.
5.3 Implications of Assumptions:
5.3.1 Implicit in the assumptions are the conditions of radial flow. Vertical flow components are induced by a control well that partially penetrates the aquifer, that is, not open to the aquifer through the full thickness of the aquifer. If vertical flow components are significant, the nearest partially penetrating observation well should be located at a distance, r, beyond which vertical flow components are negligible. See 5.3.1 of Test Method D4106 for assistance in determining the minimum distance to partially penetrating observation wells and piezometers.
5.3.2 The Theis method assumes the control well is of infinitesimal diameter. The storage in the control well may adversely affect drawdown measurements obtained in the early part of the test. See 5.3.2 of Test Method D4106 for assistance in determining the duration of the effects of well-bore storage on drawdown.
5.3.3 Application of Theis Recovery Method for Unconfined Aquifers:
5.3.3.1 Although the assumptions are applicable to artesian or confined conditions, the Theis solution may be applied to unconfined aquifers if (A) drawdown is small compared with the saturated thickness of the aquifer or if the ...
SCOPE
1.1 This test method covers an analytical procedure for determining the transmissivity of a confined aquifer. This test method is used to analyze data from the recovery of water levels following pumping or injection of water to or from a control well at a constant rate.
1.2 The analytical procedure given in this test method, along with several others, is used in conjunction with the field procedure in Test Method D4050. Guide D4043 provides information for determining hydraulic properties.
1.3 Limitations—The valid use of the Theis recovery method is limited to determination of transmissivities for aquifers in hydrogeologic settings reasonably corresponding to the assumptions of the Theis theory (see 5.2).
1.4 Units—The values stated in either SI Units or inch-pound units are to be regarded separately as standard. The values in each system may not be exact equivalents; therefore each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method.
1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless otherwise superseded by this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
